概览

NCP4894 是一款差分音频功率放大器，适用于便携式通信设备应用。NCP4894 的绝佳音频特性是手机等应用中优质声音的保证。NCP4894 的失真小于 0.01% (THD+N)，能够基于 5.0V 电源向 8.0Ω 负载提供 1.0W 的连续平均功率，在 2.6V 电源下仍然能够提供 250mW。NCP4894 提供优质音频，所需外部组件很少，功耗极低。它具有极低功耗关断模式。为了实现灵活性，关断可通过逻辑高电平或低电平启用，具体取决于 SD 模式引脚上的应用电压。NCP4894 包含的电路可防止开关转换器期间的“杂音”。为了实现最大灵活性，NCP4894 提供外部控制的增益（通过电阻）以及外部控制的开启时间（通过旁通电容器）。由于其卓越 PSRR，可以直接联接电池，不必使用 LDO。此器件采用 9 引脚触发器 CSP、Micro10 和 DFN 3x3 mm 封装。
